The median home value is $383,100, and median household income is $115,453. We use both figures to adjust labor and pricing for this page.
Charles County had 7 hail days and 50 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.75 inches across.
